CASH-REGISTER.

SPECIFICATION forming partof Letters Patent No. 673,625, dated May 7', 1901.

Application filed May 22, 1900. $erial No. 17,616. (No model.)

To all whom, it may concern:

Be it known that I, J OHN PFEIFER, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio,

have invented certain new and useful Improvements in Cash-Registers, of which the following is a specification.

My invention relates to total-adding cashregisters, and it relates more particularly to [O that class of registers described and set forth in my Patent No. 642,713, issued February 6, 1900.

The object of my invention is to provide a simple means for correctly and positively adding the different amounts indicated on the keys of the machine and transferring the amounts of one denomination to the adding.

or counting devices in the next higher denomination, so as to correctly obtain the total amount of the transactions registered on the device, while the means for accomplishing the same are extremely simple in construction and in operation. I attain thisobject by the constructions and combinations of parts hereinafter described, and shown in the accompanying drawings, in which 1 Figure 1 isa plan view of a machine embodying my invention. Fig. 2 is a front ele-' vation of a portion of the adding mechanism, 0 showing the transferring devices. Fig.3 is a view of a portion of the same with some of the parts removed or broken away. Fig. 4 is a plan View of a part'of the same. Figs. 5 to 9, inclusive, are details of parts of the machine. 5 Fig. .10 is a detail showing the pivoted lever,

one arm of which supports the movable pinion and the other arm engages the laterallymoving plate. 7

. Like parts are represented by similar let- 0 ters of reference in the several views.

In the class of register to which I have shown my invention applied a series of keys 7 are arranged in three banks a, b, and c and are adapted to represent dollars, dimes, and

5 cents. Each bank is nu mbered from l to 9 or from 10. to90, as the case may be, and the depression of any key is adapted to release and to set in operation a pivoted segmental graduated bar ob 0. An open ating-lever cl, attached to a shaftd, which extends entirelyfthrough. the machine, with the lever 61 on the outside of the inclosing case, (notshown in the drawings,) is adapted to carry the segmental graduated bars back to their normal position and in so doing to give movement to the adding mechanism. Each of these segmental bars is attached by link connections a, b c to vertically-operating racks (1 19 a which as the bars move are con respondingly moved. The keys are so arranged that when operated the segmental bar corresponding to that bank of keys will move until it contacts with the key operated, and the bars are so graduated that in their movement they will carry the racks a number of notches or teeth corresponding to the uuinher on the key. In their normal position the keys are preferably locked and they are unlocked by the operation of the lever d.

A device as thus briefly described is well known and forms no part of my present invention,'and such a device is more fully set forth in my prior patent referred to.

Adjacent to each of the racks a b c is a pinion a b 0 These pinions are each mountedon a pivoted lever, as shown at a in Fig. 3, and in their normal position they are disengaged from the racks. The pivoted 1e- I ver, however,which supports them is provided with an arm a b c", which engages with a laterally-moving bar e, which is connected to the arm d of the shaft d, so that each time the shaft (1 is moved the bar 8 is given a lateral movement, and thus brings the pinions into engagement with the racks, the arrangement being such that the pinions are thrown out of engagement with the racks as soon as the lever d has reached the limit of its forward stroke, all'of which is more fully set forth in my previous patent referred to. The pinions a b c are geared directlyto counters, those in units and tens being numbered from 1 to 9, that one for the hundreds or dollars being provided with any suitable number of counting wheels to register. larger 5 amounts. These constructions also form no part of my invention, but have heretofore been described in my prior patent referred to.

Inasmuch as the counters for the units and tens bank of keys run only from 1 to 9, it is necessary to provide means for transferring the amounts of these respectivecounters IOO to that of the next higher denomination whenever one of these counters has made a complete cycle, and I accomplish this as follows:

There is pivoted to one side of the machine a bar f, which is attached at one end to the vertically-sliding bar e, which is connected directly to the arm cl of the shaft 01 by means of the link 01 so, that each time the shaft is oscillatedthis bar f is also oscillated. There are pivoted. to a suitable part of the frame,

opposite to the tens and hundreds counters,

vibrating levers a 6 To the lower ends of these levers a b are pivoted pawl-levers or U, and at the end of these pawl-levers there are pivoted spring-actuated pawls a b", and these pawls are, when in certain positions, adapted to engage with ratchet-wheels a b forming part of the counters. Each of the counters representing units and tens is provided with These cam projections are so formed that asa single tooth o 0 which when the counterwheel has made a complete revolution is adapted to contact with the beveled end of a pivoted lever Z1 0 These levers I9 0 are pivoted at a suitable point to the frame mech-.

anism, and each carries a projecting stud Z7 which engages in a slotted opening a 12 in the pawl-levers a U. sition these pawl-levers are held by the respective studs, so that the pawls will not engage with the ratchets in the counters; but when these pivoted levers Z2 0 are moved about by the teeth-b c the studs 6 0 .will operate the pawl-levers to depress the pawls until they engage with the ratchet-teeth of the counters. The swinging levers a b are each formed with cam projections, which are engaged bysmall cam projections, preferably rollers f f 0n the vibrating lever f, so that the pawls are given a vibrating stroke at each operation of the main shaft of the machine.

the shaft (1 is returned to its normal position and the pivoted lever fis moved downward V the lever b is first operated upon, and after it has completed its movement the lever a is operated upon, the construction being such that the pawl-lever b will be vibrated to its normal position before the pawl-lever a is started. It will thus be seen that if the pawls have been thrown into operative position by the pivoted operating-levers e and 0 then as the pawl-levers are vibratedfthe counting wheels with which they engage will be moved one notch.

To provide for holding the pivoted operat ing-levers b and 0 in their operative posi- -tion,- and thus hold the pawl-levers in the proper position to engage the ratchet-teeth until after the transfer is made, each of theoperating-levers Z9 0 is provided with a slotted opening 9', as shown in Fig. 5, which 'fits over a stud gon the supporting-frame, and

' on this stud there is a washer 9 which is pressed against the lever by a spring 9 The extremity of the stud is provided with a shoulder, and there is mounted thereon a bearing In their normal po-.

plate g, which carries at the top aprojection 9 which forms a stop to prevent the operating-lever from being thrown too far, while the bearing-plate g and the spring-pressed washer g furnish a friction device to hold the operating-lever in its proper position until the transfer is made. To provide for returning these operating-levers to their normal posi tions the vibrating lever fis provided with studs or projections f which contact with the pivoted operating-levers as the vibrating bar is returned to its position, thus moving the pivoted operating levers to their normal positions, so as to be engaged by the projections b and 0 of the counters.

Any suitable means may be employed for furnishing mov'ement'to the sliding bar 6', which operates the pi'nio'ns a b c to cause them to engage and disengage the racks a b 0 the means employed in the former patent beingprefera'ble. A spring'e returns the plate e to its normal position. In order, however, to insure the action of the spring and to make the movement of the plate 'cer* tain in case the spring is not actuated, I preferably provide a swinging arm h, having on one side a projection it, (see Figs. Sand 9 for detail,) which engages with the arm e on the sliding bar 6. This swinging arm his provided on its opposite side with ca'm p'rojections h h and a camway h 7 barf is provided with a stud h, which normally stands in contact with the cam fprojection k and thus holds the swinging 'arm The vibrating h positively in its position, and th u's locks the plate e, so that the pinions 0, 6 '0 are held positively out of engagement "with the racks. As'theswinging barf moves at each stroke of the lever the stud it moves through the camway h and permits the bar 6 to be moved so as to bring the pinio'ns intoengagement I with the racks. The swinging arm h is provided at the top "with a trip-arm h", which as the vibrating barf is moved contacts with the top of said bar, brings the arm h overs'oasito positively move the plate e in case'the spring is not operated, and brings the cam projection h on the opposite side of the stud It so that as the swinging bar f descends the stud is carried along said'ca'm projection and forces the am back to its normal position'and' with it the plate. The'stud rests against the projection h when in its normal position, and thus holds the plate locked. It is obvious that the arm 'h'maybe connected pivotally to the plate, so as to operate the same in both directions, in which case the swinging arm may be used to positively operate the plate in both directions and the other operating devices may be dispensed with.

It should be no'ted't'hat each of the pawls a .'b is provided with a spring a, which is attached to the pawl-lever, so that the 'pawl will be spring-pressed against the ratchetwheel with which it engages when it is brought into operating position by the ope'r ating-lever, said spring permitting a slight giving or relaxing movement of the pawls when acting on the ratchet-wheel.

It will be seen that by the above construction at each operation of the main shaft the pivoted barf will be vibrated and will carry with it the swinging cam-arms, which in turn will produce a longitudinal movement of the pawl-levers. If the operating-levers have been moved by a complete cycle of its counter, the pawl-levers will be depressed so as to engage the ratchet-wheels of the counting device, and thus produce a movement of one step in the counting of the next higher denomination. The vibration of the pivoted barf will also cause a movement of the swinging arm h, which will positively move the plate 6 of the counter-pinions into'and out of engagement with their racks and when the pivoted bar is in its normal position will positively hold said pinions out of engagement with their racks.

Having thus described my invention, I claim- 1. The combination witha series of counting devices, and means for operating the same independent of each other, a pivoted operating-lever adapted to be engaged and moved by the counting device of a lower denomination, and a pivoted longitudinallyvmoving pawl-lever having a pivoted hook end adapted to engage and move the. counter of a higher denomination, a connection between said operating-lever and said pivoted pawl-lever, means as described for holding said operating-lever and pawl-lever in their normal operating positions and for producinga longitudinal movement of said pawlleverwhile in this position, substantially as specified.

2.
